An Anti-circuit Control Attack Method Based on Fragmentation-reassembly in Anonymous Network

Abstract

Aiming at the current problem that the anonymous network controlled through circuit reconfiguration, we propose a method of anti-circuit control attack in anonymous network based on fragmentation-reassembly in this paper. The data segment is divided by random fragmentation-reassembly method according to L interval, and two data fragments are combined into a new data segment, then the new data segment will be sent to the receiver. After the receiver receives all segments, it reassembles the data segments. Experiment and theoretical analysis show that the method proposed in this paper has more types of anti-circuit control attack than the redundancy method, and consumes less resources and provides data reorganization security.
